The Architektur Museum der Tum is a Munich museum dedicated to architecture. It is one of the four museums of the "Pinakothek der Moderne", one of the most important museums of modern and contemporary art in Germany, which contains the Museum of Modern and Contemporary Art, the Museum of Design, the Cabinet of Drawings and of Graphics and, in fact, the Museum of Architecture. The Architektur Museum der Tum was born in 1868 as a collection of drawings, projects and scale models for the teaching of the New Polytechnic School, today the Technical University of Munich (of which it still belongs today, as can be seen from the acronym "Tum") . With the evolution of the didactic techniques of architecture, the collection soon became a historical collection in itself, the nucleus of today's museum, officially founded in 1975. It is the largest collection of architecture in Germany. The inventory of the collection archive includes around 600,000 drawings and plans, over 200,000 original photographs and numerous models by over a thousand architects. The focus of the collection is on 19th, 20th and 21st century architecture and contains works by architects such as Gottfried von Neureuther, Leo von Klenze, Friedrich von Gärtner, Theodor Fischer, Richard Riemerschmid and Paul Schneider-Esleben. The museum does not have its own permanent collection, but organizes regular temporary exhibitions within the Pinakothek der Moderne.
